Seems like this has already been fixed in vobject: py-vobject/vobject#21

But there hasn't been a release since this fix (so caldav hasn't pulled it in yet either).

vobject v0.9.8 has been released containing the fix and caldav doesn't depend on a specific version of it, so this might already be fixed? @rgerbranda are you still seeing this?

I did not see the warning anymore, so problem seems to be solved.
